Q13: Will your masks protect against viruses and/ or other pathogens?

Our filter blocks 99.4% of particulates down to .1 micron. This rate is known to be effective toward most airborne pathogens.

Please be aware that our M Plus and M Cross masks only filter the air being breathed in and not the air being breathed out. Because of this, they will only provide filtration for those wearing the mask. If you believe you have been infected, our masks will not protect those around you from the spread of infection. There are multiple ways the COVID-19 virus can be contracted, and we recommend following all prevention measures provided by the CDC and WHO.
